Hello,

I would like to know why on the last release there is no more

sys.implementation.mpy available?

On 1.18 I was able to import the sys and then just print:

sys.implementation.mpy & 0xff

What has changed on 1.19.1 and how can I fix this problem?

Thank you

Ok I have found the answer.

Maybe it could be usefull for some one, so the sollution is really simple:

the .mpy attribute has changed in 1.19 so now it is _mpy

this works:

sys.implementation._mpy & 0xff
6

Yes, we realised that to be compatible with CPython, our "extended" attributes needed to have a leading underscore.
